Django AWS S3 с использованием Boto с компрессором не сжимает UncompressableFileError

Следуя это руководство, и эти [1] [2], я попытался установить статическое хранилище на AWS S3, используя django-storage Boto.

При выполнении collectstatic команда успешно собирает в STATIC_ROOT. Однако файлы не загружаются на S3, а сервер не может их обслуживать. Возвращается ошибка 500. Глядя на журналы:

Сообщение об ошибке:

UncompressableFileError: 'https://<myapp>.s3.amazonaws.com/static/oscar/css/styles.css' could not be found in the COMPRESS_ROOT '/var/www/<myappname>/static' or with staticfiles.

EDIT:

Я также изменил STATIC_URL на http://%s/ % AWS_S3_CUSTOM_DOMAIN, и я получаю ту же ошибку, за исключением того, что он все еще ищет в https, но COMPRESS_URL - http.

UncompressableFileError: 'https://<myappname>.s3.amazonaws.com/static/oscar/css/styles.css' isn't accessible via COMPRESS_URL ('http://<myappname>.s3.amazonaws.com/') and can't be compressed

Это несовместимость с компрессором и Boto?
